Is it normal to be bored and pissed off while going through puberty?

I am a 15 year old boy and I think life is so boring. I dont get the same kick and pleasure out of things that I used to. When I was younger, when I tried something knew I loved it, now its just boring and normal. I only socialize within school, but dont know how to take it further than that. I stay home and watch tv on the weekends. Sports are not as pleasurable as they used to be. I used to love sports and I couldn't live without them, now I get pissed every time I go to sports practice. WHAT IS HAPPENING!!!!!!!!!!!!!!! WHY IS LIFE SO BORING!!!!!!!!!!!!! SCHOOL IS BORING!!!!!!!!!!!!! EVERYTHING IS!!!!!!
